Transcript of "01b01 01"

  1. 1. - 1 - Overview Vehicle Composition A vehicle consists of the following components: 1. Engine • Gasoline or Diesel engine 2. Drive train
  2. 2. - 2 - 3. Chassis • Suspension • Steering • Brake
  3. 3. - 3 - 4. Engine electrical 5. Body electrical 6. Body (1/1)
  4. 4. - 4 - Vehicle Classification Classification by Motive Power Vehicles can be classified by the following types of motive power: Gasoline engine vehicle Diesel engine vehicle Hybrid vehicle Electric vehicle Fuel cell hybrid vehicle (1/6) Gasoline engine vehicle This type of vehicle runs on an engine that uses gasoline fuel. Because gasoline engines produce high power yet come in a compact package, they are widely used in passenger vehicles. Similar engines are also used on the CNG engine, the LPG engine and alcohol engine, which use different types of fuel. CNG: Compressed Natural Gas LPG: Liquefied Petroleum Gas Engine Fuel tank (gasoline) (2/6) Diesel engine vehicle This type of vehicle runs on an engine that uses diesel fuel. Because diesel engines produce large torque and offer good fuel economy, they are widely used in trucks and SUVs. SUV: Sports Utility Vehicle Engine Fuel tank (diesel fuel) (3/6)
  5. 5. - 5 - Engine Inverter Transaxle Converter Battery Hybrid vehicle This type of vehicle is equipped with different types of motive power, such as a gasoline engine and an electric motor. Because the gasoline engine generates electricity, this type of vehicle does not require an external source for recharging the battery. System of wheel driver uses 270V, on the other hand, other electric 12V. For example, during start- off, it uses an electric motor that produces high power despite a low speed. When the vehicle picks up speed, it operates the gasoline engine that is more efficient at higher speeds. By making the best use of both types of motive force in this manner, it is effective in reducing exhaust emission and improving fuel economy. • The diagram indicates the Toyota hybrid system (gasoline and electric motor). (4/6) Electric vehicle (EV) This vehicle uses the power of the batteries to operate the electric motor. Instead of using fuel, the batteries require recharging. It offers many advantages, including zero emissions and low noise during operation. System of wheel drive uses 290V, on the other hand, other electric 12V. • The diagram indicates Toyota EV system. Power control unit Electric motor Battery (5/6) Fuel cell hybrid vehicle (FCHV) This electric vehicle uses the electric energy that is created when the hydrogen fuel reacts with the oxygen in the air to form water. Because it emits only water, this is considered to be the ultimate form of low- pollution vehicle, and is anticipated to become the motive power for the next generation. • The diagram indicates Toyota fuel cell hybrid system. Power control unit Electric motor Fuel cell stack Hydrogen storage system Secondary battery (6/6)
  6. 6. - 6 - Classification by Drive Method Vehicles can be classified by the position of the engine and drive wheels, and the number of drive wheels. FF (Front-engine, Front-drive) Because a FF vehicle does not have a propeller shaft, a spacious interior can be realized, thus achieving excellent comfort. FR (Front-engine, Rear-drive) Because a FR vehicle has a good weight balance, it excels in controllability and stability. MR (Midship-engine, Rear-drive) Because a MR vehicle has a good weight balance on the front and rear axles, it excels in controllability. 4WD (4-Wheels Drive) Because a 4WD vehicle drives with four wheels, it can operate under poor conditions in a stable manner. Its weight is greater than that of other types of vehicles. (1/1)
